Follow-up of the rehabilitation works on the RN1

Follow-up of the rehabilitation works on the RN1

As part of the maintenance of the national roads of the corridor, DPCR has launched several rehabilitation projects that started with the PK21-PK22 section (RN1) and the Doraleh traffic circle (RN3).

Received a few months ago, we have undertaken new repair works at Omar Jagac and Iskoutir on the vital axis of the economy of the Republic of Djibouti serving Ethiopia. Indeed, the roadway has been progressively impacted by the crossing of the wadi but also by the dense and regular passage of overloaded heavy trucks using this corridor.

These works include several phases, namely:
1. Repair of potholes and crossings (between Arta and Grand Barra in the southern Djibouti desert);
2. Rehabilitation of the flexible invert with a complete resurfacing of the pavement from the base course as well as an optimal reinforcement of the invert (between PK56-PK57) ;
3. Renewal of the asphalt pavement over a 1km stretch (between KP69-PK70);
a. Laying of 7 cm thick bituminous gravel
b. Construction of 5 cm thick bituminous concrete
4. Application of a 5 cm thick asphalt over a 1.5 km stretch (PK70-PK71.5).

The improvement of the Omar Jagac & Iskoutir sections is essential for the goods and users using the RN1 daily.
These 2.7 km long works were financed by DPCR and entrusted to the Djibouti Roads Agency for a total duration of 4 months.

These pothole repair activities will allow:
- A reduction in the passage time of trucks and users serving the hinterland;
- A net decrease in transport costs through the reduction of accidents;
- Restore the comfort and safety of users;
- To reinforce the pavement structure in order to improve the longevity of these sections;

It is to be reminded that the RN1 concentrates over 90% of the overland exchanges of heavy trucks composed - among others - of tridem, tandem and oil trucks. The DPCR team carries out daily control and monitoring missions of the works to ensure strict compliance with the standards in force.
